Before taking probes L60 or L61 into the Ex-zone 0, connect the
grounding set in the following order!
1. Connect the probe L60 or L61 by means of the M4 screw. Screw
the M4 screw into the side thread on the casing of the probe and
tighten it with a suitable tool.
2. Clamp the grounding clamp to the local equipotential bonding
conductor. Connect and position the grounding set in the way that
it also secures the probe from falling (in order to prevent friction
or impact sparks if the probe should drop onto a metal surface).
3. Now, the probe can be taken into the Ex-zone 0!
The grounding cable must not be rolled up in a hazardous area!
